I've got a chart that needs some opinions

Hey guys. I made up this plot using Blaubox. I was curious to know what would happen if my 9 year old MTX Black Gold 10" sub was to be compared to my new $20 Roadmaster 8" Wal-Mart sub. So after some research, i found the phone number of the Roadmaster company and got my hands on the t/s parameters. Strangely enough the optimal box size for this sub is 1.25 cu ft. That just seems really big for a 100w rms 8" sub, but any way... So here are the results i got using the enclsure my MTX is in right now Vs what the 8" is going to be in. Let me know what i'm lookin at here. Just something i did for fun, lookin for a few opinions about the 2 subs. Based on this chart alone, which would you think is the better sub. My vote is the MTX, seems to have a nice smooth curve, not so sharp and peaky.

auex is absolutely right.  Plus, it looks like you did not input the optimum size enclosure data for your "Roadking" in the test. One interesting thing about your graphs is if the port tuning frequency  is 35 Hz, then why is your optimum performance up around 60 or 80 Hz?  Where is the 35 Hz going?  Why does the program predict a relatively flat response at about -3db out past 500 Hz?  The Blaubox program was written with pre-determined parameters for Blaupunkt woofers in it, by the way.

Even if your response curve is somewhat accurate, I predict those $20 Wal Mart POS drivers would be Road KILL after about a week - if they last that long.  I believe these "speakers" (and I use the term loosly) are actually made by the same Chinese company that made the old Mobile Authority "Thump" line.  These were aptly named, as "Thump" is the sound they made when you tossed them into the garbage can after they blew at 50% of their supposedly rated power input or wore out and started sounding like cardboard boxes after about three CDs.

Here is the catalog page for those Dayton subs, which are high quality, by the way.    http://www.partsexpress.com/pdf/catalog04/188pec03.pdf

There is a good calculator here     http://www.bcae1.com/                             Scroll down along the right menu toward the bottom to get to 116-Speaker Enclosure Calculations.  At the bottom of that page is a calculator.  Plug in the parameters of the speaker and see what you get.
